The script says:
“You enabled Memcache caching in the Server Settings but script could not connect to Memcache using parameters specified in your script. Check the Memcache server and accuracy of its connection settings in the Script Settings. Otherwise, enable file caching in in the Script Settings.”

Memcache PHP extension is installed? @phuongdzu
